Abstract

A cannula sealing shield assembly comprises a cannula assembly including a cannula having a proximal end, a distal end and a lumen therethrough. A hub having an open proximal end and a distal end is joined to the proximal end of the cannula so that the lumen is in fluid communication with the open proximal end of the hub. A shield includes an open proximal end, an open distal end and a side wall therebetween defining a recess. The shield is removably connected to the cannula assembly so that the distal end of the cannula is contained within the recess. A seal plug includes a proximal end and a distal end. The seal plug has a distal position wherein the seal plug projects distally outwardly from the distal end of the shield for telescoping movement from the distal position to a proximal position. The seal plug including structure for sealing the cannula to prevent unpressurized fluid communication between the lumen and the exterior of the shield when the seal plug is in the proximal position.
